This article covers ZOTAC GAMING GeForce RTX 3080 Trinity OC LHR グラフィックスボード ZT-A30800J-10PLHR VD7781.

Overview

The ZOTAC GAMING GeForce RTX 3080 Trinity OC LHR ZT-A30800J-10PLHR VD7781 is a graphics card built on NVIDIA's second-generation RTX architecture (Ampere). It comes equipped with 10GB of GDDR6X video memory across a 320-bit bus, and the boost clock is factory-overclocked to 1725MHz. The LHR (Lite Hash Rate) designation means Ethereum mining efficiency is intentionally limited, making this card more accessible to gamers and creators rather than cryptocurrency miners.
With 8704 CUDA cores, 68 RT cores, and 272 Tensor cores, this card delivers impressive compute power for both gaming and creative workloads. The memory bandwidth sits at roughly 760 GB/s, which gives it an edge in 4K gaming scenarios compared to many newer mid-range cards. The IceStorm 2.0 cooling system uses three 90mm fans and a heatsink with three heatpipes to keep thermals under control during extended gaming sessions.
The RTX 3080 was originally announced in September 2020 and sits in the mid-high range of the RTX 30 series. Despite being a few years old, it remains a capable performer for modern titles at 4K resolution, especially when paired with DLSS. The ZOTAC Trinity series is known for offering a solid balance of price and performance, and this OC model adds a modest factory overclock out of the box.

Compatibility Guide

This graphics card uses a PCI-Express x16 interface and is compatible with PCIe 3.0 motherboards, though it benefits from PCIe 4.0 bandwidth for certain workloads.

  • Power supply requirements: two 8-pin PCIe power connectors are required. ZOTAC recommends a 700W PSU minimum, but a quality 750W or 850W unit is advisable for headroom with a high-end CPU.
  • Physical dimensions: approximately 31.8 cm (12.5 inches) in length and 2.5 slots thick. Always measure your case clearance before purchase. Most mid-tower ATX cases accommodate this length, but compact or mini-ITX cases likely will not.
  • Video outputs: three DisplayPort 1.4a and one HDMI 2.1 port. This allows for 4K at 144Hz or 8K at 60Hz output. HDMI 2.1 is especially useful for connecting to modern 4K high-refresh-rate TVs.
  • Motherboard clearance: because the card is roughly 2.5 slots wide, it may block adjacent PCIe slots or SATA ports on some motherboards. Check your motherboard layout before installation.

Product Info

The ZOTAC GAMING GeForce RTX 3080 Trinity OC LHR ZT-A30800J-10PLHR VD7781 is powered by the GA102 GPU die. It features a base clock of 1440MHz and a boost clock of 1725MHz, slightly higher than the reference 1710MHz.

  • Memory: 10GB GDDR6X at 19 Gbps effective clock, 320-bit bus, ~760 GB/s bandwidth.
  • TBP (Total Board Power): 320 watts. Idle power consumption is typically under 30W thanks to efficient power management.
  • Cooling: IceStorm 2.0 system with three 90mm fans, three copper heatpipes, and an aluminum fin array. The fans support semi-passive operation, stopping completely under low load or idle.
  • Build: metal backplate adds rigidity and some passive cooling. The card uses a dual-slot-plus design (effectively 2.5 slots).
  • Warranty: 1 year for the Japanese authorized distribution channel (VD7781 marking), with potential extension upon product registration.
  • Market positioning: mid-high tier. As of late 2024, this card is no longer widely available as new stock, but it remains popular on the used market due to its strong 4K gaming performance at a competitive price.

Best Use Cases

  • 4K 60fps gamers: The RTX 3080 delivers smooth 60fps gameplay in most modern AAA titles at 4K resolution with high settings. For ray-traced titles, enabling DLSS Quality mode is recommended to maintain frame rates. This card is a great choice for players who want to experience 4K without jumping to the RTX 4080/4090 price bracket.
  • 1440p high-refresh-rate enthusiasts: At 1440p, this card easily pushes 100-144fps in competitive shooters and open-world games. It's ideal for users with a 1440p 144Hz or 165Hz monitor who want to max out graphical settings while maintaining high frame rates.
  • Video editors and 3D artists: The large number of CUDA cores accelerates rendering in Blender, Maya, and video encoding in Premiere Pro and DaVinci Resolve. The 10GB VRAM handles 4K timelines well, though 8K or complex 3D scenes may push its limits.
  • Budget-conscious builders targeting 4K: Compared to similarly priced newer GPUs, the RTX 3080 offers superior memory bandwidth and raw compute. It's an excellent choice for DIY builders who can find a well-maintained used unit and pair it with a sufficient PSU and case.

Things to Consider

  • Power draw and heat output are substantial. Under full gaming load, the card can draw around 300-320W, and the IceStorm fans become audible. Ensure your case has good airflow and at least one intake and one exhaust fan. A high-quality 750W+ PSU is strongly recommended.
  • Card length (~31.8 cm) is a strict physical const
